Objective To determine the effectivity of 5-azacytidine(5-Aza) inducing the cardiomyogenic SCs were isolated and purified from Sprague-Dawley (SD) rats. Some BMSCs were induced with 5-Aza,group Ⅰ was not induced with 5-Aza and the third generation of cells were used for the next experiment; group Ⅱ were cultured and induced with 5-Aza( 10 μmol/L) at the third day of the culture for 24 h; group Ⅲ were induced with 5-Aza( 10 μmol/L) for 24 h when the third generation of cell were fused; group Ⅳ were induced with 5-Aza( 10 μmol/L) for 24h at the third day of primary cuhure,which were induced with 5-Aza( 10 μmol/L) for 24 h before the third gener-phosis was found in the BMSCs among groups. CD34 was negatively expressed and CD29 and CD44 were positively gle 5-Aza inducing group(group Ⅲ ) was much higher than that in no 5-Aza inducing group( group Ⅰ ) [ MHC : (6. 82±2.05 ) % vs (3.61±1.14) % ], cTnI: (5.63±1.86) % vs (2.76±0.82) %, P < 0.05 ], but was significantly lower than the percentage in the double 5-Aza inducing group ( group Ⅳ ) [ MHC : ( 12.18±3.16) % vs ( 6.82±2. 05)% ] ,cTni:(9.93±2.79)% vs(5.63±1.86)% ,P<0.05]. Conclusions 5-Aza could promote the cardio-myogenic differentiation of BMSCs in a "Cardiac-like" Milieu. 5-Aza double induing is better than the single indu-cing.

Objective To investigate the effects of dexamethasone(DEX)on the secretion of interleukin (IL)-17 and interferon(IFN)-γ and the proportion of Th17,Tc17,Th1 ,Tc1 cells in peripheral blood mononuclear cells(PBMCs)of patients with systemic lupus erythematosus(SLE). Methods Thirty hospitalized SLE patients were recruited and twenty-two healthy volunteers were recruited as healthy controls. PBMCs were separated from SLE patients and healthy controls and then was cultured in vitro by medium or PMA/Ionomycin or PMA/Ionomycin +dexamethasone for six hours. Four- color immunofluorescent staining and flow cytometric assay were used to analyze the percentage of Th17,Tc17,Th1,Tc1 cells in PBMCs. Concentrations of IL-17 and IFN-γ in plasma and the supernatants of PBMCs which were cultured for 24 hours were measured by enzyme linked immunosorbent assay (ELISA). Results The plasma concentrations of IL-17 and IFN-γwere elevated in SLE patients as compared to the controls(P ＜ 0.05). No significant differences were observed between patients and controls for the spontaneous production of IL-17 and IFN-γ or percentage of T subsets expressed by PBMCs. After the stimulation of PMA,compared with the controls,the level of IL-17 was significantly elevated in the supematants of PBMCs and the percentages of Th17 and Tc1 in SLE patients increased significantly(P ＜ 0. 05). However,there showed no significant differences between SLE patients and the controls for the percentages of Th1 and Tc17 cells. DEX could significantly decrease the production of IL-17(P ＜ 0. 01)and the percentages of Th17,Tc1 cells by the active PBMCs(P ＜ 0. 05). Conclusions There is abnormal expression of T subset cells and their cytokines in vivo of SLE patients. DEX can interfere with immunological pathological process in the cytokine network imbalance of SLE patients and shows powerful inhibition of IL - 17. Our results may provide some laboratory evidence for the clinical application of corticosteroids.

AIM: To explored the treatment effects of retinal laser photocoagulation and the applications of color Doppler flow imaging(CDFI) in the diabetic retinopathy.METHODS: We collected 60 patients(120 eyes) with diabetic retinopathy(Ⅲ~Ⅳstage) from February 2013 to February 2014 in Anyang Eye Hospital admitted in fundus disease department.The health control (HC) group of 55 normal people was established simultaneously.Ocular blood flow velocity of the 55 normal people (110 eyes) and the 60 patients (120 eyes) was examined by CDFI of central retinal artery (CRA) and posterior ciliary artery (PCAs) using the PHILIPS HD6.Peak systolic velocity(PSV) was recorded.The examinations of CDFI, electroretinogram(ERG) and the vision were performed in pre-operation, 1,7d, 1, 3 and 6mo postoperatively.RESULTS: Compared the PSV of CRA of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the PSV of CRA of the DR group after photocoagulation with the data before, there was a significant difference(P<0.05).Compared the PSV of PCAs of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the PSV of PCAs of the DR group after photocoagulation with the data before, there was a significant difference at 1d postoperatively(P<0.05), there was no significant difference at 7d, 1, 3 and 6mo(P>0.05).Compared the aA and bA of ERG of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05).Compared the aA and bA of ERG of the DR group after photocoagulation with the data before, there was a significant difference(P<0.05).Compared the aT and bT of ERG of the DR group before and after photocoagulation to the data of the HC group, there was a significant difference(P<0.05);compared the aT and bT of ERG of the group DR after photocoagulation with the data before, there was no significant difference(P>0.05).The vision of 49 cases(98 eyes) was improved 1 to 3 rows, the effective rate was 82%.The vision of 11 cases(22 eyes) remained constant.CONCLUSION: Retinal laser photocoagulation is an effective treatment to diabetic retinopathy patients, which can significantly reduce the peak systolic velocity of the central retinal artery, improve and stabilize the condition, protect visual function in long-term clinical effect.Color doppler flow imaging can observe the changes of ocular vessel flow velocity in diabetic` eyes noninvasively, repeatedly and in real time, providing a basis for clinical treatments.

Objective To understand the direct economic burden of healthcare-associated infection(HAI)due to multidrug-resistant organisms(MDROs).Methods Computer retrieval of CNKI,Wanfang,VIP,PubMed,Sci-enceDirect,and Cochrane databases on literatures about economic burden of MDRO HAI at home and abroad were performed,the retrieval time was from database establishment to December 2015,systematic evaluation of the liter-atures was obtained.Results According to the inclusion and exclusion criteria,as well as through Newcastle-Otta-wa Scale (NOS)for evaluating the literatures,19 literatures were included.In 12 studies about methicillin-resistant Staphylococcusaureus infection,the direct economic cost varied from $916.61 to $62908.00;in 4 studies about MDRO Acinetobacterbaumannii infection,the direct economic cost varied from$4644.00 to $98575.00.Direct economic cost due to extended-spectrumβ-lactamases-producing Enterobacteriaceae was $2824.14-$30093.00. Conclusion MDRO HAI will increase economic cost of both hospitals and patients,prevention and control measures should be taken .

Objective To observe the changes in ovary blood supply of the tuberculous pelvic inflammation patient before and after treatment by color Doppler to explore the influences of tuberculous pelvic inflammation on uterus and ovary functions from hemodynamic aspect as well as the rehabilitation of uterus and ovary functions after treatment.Methods The 17 tuberculous pelvic inflammation patients in the observation group and 17 healthy women at child-bearing period underwent color Doppler examination,and such indexes were measured as the peak systolic flow velocities of uterine artery and arteria ovarica (Vmax),resistance index (RI) and pulsatility index (PI).The measure values at all the stages were compared in the observation group,and then contrasted with those in the control group.The rehabilitation of ovary function was evaluated according to the measure values.Results The observation group had the Vmaxs of rami ovarii arteriae uterinae and arteria ovarica 3 months after treatment higher than those before treatment,and the Vmaxs of rami ovarii arteriae uterinae and arteria ovarica 1 a were significantly higher than those 6 months after treatment.The Vmaxs of rami ovarii arteriae uterinae and arteria ovarica in the observation group 3 months,6 months,1 a and 1.5 a after treatment were all higher statistically than those in the control group at corresponding periods.The observation group had the measure values of PI and RI before treatment as well as 3 months and 6 months after treatment obviously higher than those in the control group.The measure values of PI and RI 1 and 1.5 a after treatment in the observation group were also higher than those in the control group.Conclusion Uterine artery and arteria ovarica may have hemodynamic changes before and after pelvic tuberculosis treatment.Measuring the blood flow parameters of uterine artery and arteria ovarica before and after pelvic tuberculosis treatment contributes to evaluating pelvic tuberculosis treatment efficacy and predicting ovarian function rehabilitation after treatment.

The study was aimed to explore the effects of recombination human granulocyte colony-stimulating factor (rhG-CSF) on Th17 cells in donors' peripheral blood (GPB) and bone marrow grafts (GBM). 25 healthy donors were injected subcutaneously with rhG-CSF 5 µg/(kg·d) for 5 consecutive days. GBM and GPB were harvested after injection on day 4 and 5 respectively. Some of these donors' steady-state bone marrow (SSBM) and steady-state peripheral blood (SSPB) were harvested before rhG-CSF injection. The changes of IL-17 secreted by T cells in donor BM and PB before and after mobilization were detected by flow cytometry. The results showed that the ability to secrete IL-17 from CD4(+) T cells and CD8(+) T cells in GBM was significantly lower than those in SSBM (GBM vs SSBM Th17/CD4(+) T, 0.74% ± 0.27% vs 1.78% ± 1.19%, p < 0.05; Tc17/CD8(+)T, 0.19% ± 0.16% vs 0.36% ± 0.37%, p < 0.05), changes in peripheral blood and bone marrow were same (GPB vs SSPB Th17/CD4(+) T, 1.82% ± 0.91% vs 3.26% ± 1.89%, p < 0.01; Tc17/CD8(+) T, 0.21% ± 0.17% vs 0.44% ± 0.28%, p < 0.01). The ratios of Th17/CD4(+) T and Tc17/CD8(+) T in GPB were higher than in GBM (p < 0.05, p < 0.01). It is concluded that rhG-CSF in vivo can inhibit the generation of Th17 cells both in bone marrow and peripheral blood grafts, and it may be partial reason for GPB/GBM mixed transplantation without increasing the GVHD incidence.
